| 摘 要： | 分析了1990年以来在祁连山断裂带上发生的7次地震前，嘉峪关气氡观测点和酒泉水氡的变化情况，发现在1990年10月20日天祝6．2级地震、1992年1月12日嘉峪关5．4级地震、1995年7月22日永登5．8级地震和2002年12月14日玉门5．9级地震前，嘉峪关气氡观测点均记录到短期的破年变异常，而酒泉水氡在玉门地震前为明显的突变型中期异常。

| Abstract: | The varieties of escaping radon at Jiayuguan and radon in groundwater at Jiuquan are analyzed before seven times earthquakes occurred at Qilianshan rupture belt since 1990. The results show that the regularity of annual variation of the escaping radon at Jiayuguan observatory was broken in short term before Tianzhu MS 6.2 earthquake on October 20, 1990, the Jiayuguan MS 5.4 earthquake on January 12, 1992, the Yongdeng MS 5.8 earthquake on July 22, 1995 and the Yumen MS 5.9 earthquake on December 14, 2002. The radon in groundwater at Jiuquan evidently shows middle term anomaly of sudden variety before the Yumen earthquake. |
